Hi my problem its i start live antergos from iso in usb to install antergos in my notebook and dont have icon of networkmanager, i go to network from settings and doesnt see any tipe of connection posible, with older iso i dont have this problem, what should i do? sorry for my english maybe have errors i originally speak spanish. Thanks

First off, I would give a try to a different machine to see if the problem insists. There are quite a few connection issues reported latetly (at least on already installed systems).
Also, play around with these commands to see if they have any effect…sudo systemctl stop NetworkManager.servicesudo systemctl start NetworkManager.servicesudo service network-manager restart
Cheers
